nearly a week since the newtown tragedy. and in light of that shooting, we'll take you to a school that could be, could be the safest in the country. >> all week, abc has been devoting coverage to solutions to the gun violence and school security issues around the country. this is fascinating, that particular school, the lengths that they go to. we may be able to learn something from that school. >>> also this morning, from one major airline hub to another, a strong winter storm system blasted denver and now headed to, yep, the windy city of chicago. the blinding whiteout conditions and how this storm could have a ripple effect on your travel plans as we get closer to christmas. >>> later this half hour, the doomsday business. special, custom-built bunkers for people who really do believe they can survive the end of the world in comfort. >> wow. tomorrow, the mayan calendar, 12-21-12, it could all be over tomorrow. it's been a pleasure. i'll see you in whatever life comes after this. it's been real. i'm looking forward to it
